"So much more than just a calculator I got this app to use as a scientific calculator but it's so much more than that. The interface and menu options mean that I can calculate almost anything without knowing the formula. The unit conversion and tax calculation shortcuts are particularly useful for me. Very happy, a great investment. A+""

"Fantastic! A Quick & Powerful Calculating Tool for your EVERY Need! CustomCalc is by far the best Calculating App on the market hands down! This is a powerhouse Application that I will use daily. It has many unique functions that help both Business professionals, students and the scientific minded as well. It is fully customizable and can perform right along with many of today’s leading financial and scientific calculators. You can say goodbye to lugging these bad boys around anymore! Thank you! I love the currency exchange feature as well as the unit conversions and Trigonometric/Algebraic mode. I have been playing with it for a few days now and I honestly don’t think the developers of this app missed a thing within "
